Intraocular Infection Intraocular Tumors 859

The prognosis of CMV retinitis depends on location of the disease.
Involvement of the optic nerve or macula leads to profound visual
loss. Unless the immune system is reconstituted, the ultimate prog-
nosis is very poor. With immune reconstitution, prognosis can be
very favorable. Complications include retinal detachment, cataract
and immune reconstitution uveitis.

Intraocular Tumors...................................


DEVRON H. CHAR, MD


history & physical
■Asymptomatic; decreased vision; rarely unilateral cataract, or painful
red eye.
tests
■Most diagnosed with non-invasive tests
■Intraocular lymphoma may be diagnosed by vitrectomy cytology.
■Retinal angioma patients should have a molecular genetic test for
VHL.
differential diagnosis
■Intraocular tumors are rare.
■An apparent intraocular tumor is more likely hemorrhage asso-
ciated with an idiopathic age-related macular degeneration or a
localized choroidal hemorrhage (hypertension or after recent eye
sugery).
■Other benign conditions including scleritis can simulate an ocular
malignancy.
■Most common primary intraocular neoplasm in ambulatory adults
is uveal melanoma (incidence of∼7/1,000,000/year); mainly older
Caucasians.
■<1% of uveal melanomas present simultaneously with detectable
metastases.
■Metastases to the choroid can be the first sign of a systemic malig-
nancy.
■∼10% of breast choroid metastases present before discovery of pri-
mary tumor.
■∼90% of renal or lung patients have diagnosis of ocular tumor prior
to discovery of primary lesion.
■Metastases non-pigmented; clinical and ancillary imaging usually
diagnostic
